Abstract
The utility model discloses a self-adaptive gantry framework of a gantry-moving type machine tool. The self-adaptive gantry framework comprises a left vertical post, a right vertical post, a left sliding seat and a right sliding seat, wherein the left sliding seat and the right sliding seat are respectively positioned on longitudinal guide rails, the longitudinal guide rails are arranged at the two sides of a lathe bed, the right vertical post is in rigid fastening connection with the sliding seats, a support plate is arranged between the left vertical post and the sliding seats, is in rigid fastening connection with the vertical post above the support plate and is horizontally matched with the sliding seat below the support plate in a sliding manner; and an internal circulation pressure balancing oil cylinder is arranged at the outer side of the left sliding seat, and the outer end of the support plate is connected with a piston rod of the oil cylinder. During the working of the machine tool, when the comprehensive stress of the gantry framework reaches a certain value, the oil cylinder automatically unloads, so that the normal running of a gantry is ensured, and the machining precision of the machine tool is not affected. The self-adaptive gantry framework is simple in structure and low in cost, and is practical and convenient to debug and install, and the manufacturing difficulty and the installation and debugging difficulty of the machine tool are reduced.
Description
Technical field
The utility model relates to a kind of gantry frame, and what be specifically related to is the gantry frame on a kind of movable gantry lathe, particularly a kind of large-sized gantry framework with adaptive ability.
Background technology
That mostly the movable gantry lathe is is large-scale, heavy type and superduty process equipment, and the gantry frame weight on the lathe is big and stroke is long.In the prior art; The gantry frame of this type lathe mainly is rigidly connected by left and right pillar, back timber and slide and forms; The slide of left and right pillar below is slidingly matched with the fixed guide on lathe bed both sides respectively; Framework integral body is bearing on the lathe bed, and gantry frame moves forward and backward along bed ways, implements the processing to workpiece.The gantry frame of this structure; Require the integral rigidity and the locating accuracy thereof of the depth of parallelism, gantry frame of lathe bed both sides guide rail all very high; The portable lathe of large-sized gantry of particularly high-speed, high accuracy, high strength and overlength stroke, its accuracy of manufacture is higher with the installation accuracy requirement.Its reason is, in the installation of lathe and in service, lathe self variations in temperature can cause the physical deformation that gantry frame and bed ways expand with heat and contract with cold in the variation of environment temperature and the processing work process; This distortion must influence machine finish; When deflection is excessive, the damage of rigid connector can be caused, also lathe can be damaged when serious; As not strict design, manufacturing, installation and debugging, above-mentioned consequence then is difficult to avoid.And this situation ubiquity on existing large-scale, heavy movable gantry lathe.
Summary of the invention
The purpose of the utility model is to provide a kind of gantry frame that is adapted to high-speed, high accuracy, high strength and the portable lathe of overlength stroke large-sized gantry; It can conform variation of variation of temperature and stressed size; Adjust the position voluntarily; Guarantee the machining accuracy of lathe, thereby reduce the manufacture difficulty and the Installation and Debugging difficulty of lathe.
The technical scheme that realizes above-mentioned purpose is: a kind of self adaptation gantry frame of movable gantry lathe; Comprise left and right pillar and left and right sides slide; About two slides lay respectively on the longitudinal rail on lathe bed both sides, it is characterized in that: the column on the right rigidly fixes with slide and is connected; A supporting plate is installed between the column on the left side and the slide, and this supporting plate rigidly fixes and is connected with the column of its top, forms laterally with the slide of its below to be slidingly matched; The outside of left side slide is extended with a holder, and an interior cyclic balance oil pressure cylinder is installed on this holder, and the outer end of supporting plate is connected with the piston rod of oil cylinder.
There are two horizontal parallel guide rails said left slide upper surface, matches with cross slide way on the left slide in the lower surface of said supporting plate.
During work, gantry frame integral body vertically moves along bed ways.If because factors such as stressed and variations in temperature make gantry frame in horizontal generation internal stress in the manufacturing of two bed ways and installation accuracy error and the workpiece processing; So; When this stress reaches certain value; Overflow valve in the interior cyclic balance oil pressure cylinder will be opened automatically, carries out off-load; Meanwhile, the column on the left side certain distance that will under the guiding of supporting plate, outwards squint is adjusted the position automatically.The structural rigidity of gantry frame does not weaken during off-load, has so both guaranteed the normal operation at gantry, does not influence the machining accuracy of lathe again.
The utility model is simple in structure, practical, and is with low cost, debugs easy for installationly, reduced the manufacture difficulty and the Installation and Debugging difficulty of lathe, for the precision that improves large-scale and heavy movable gantry lathe provides a kind of guarantee.
Description of drawings
Fig. 1 is the organigram of an embodiment of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is that the B of Fig. 1 is to view.
Among the figure: 1. right slide, 2. right column, 3. back timber, 4. left column, 5. supporting plate, 6. left slide, 7. holder, 8. in cyclic balance oil pressure cylinder, 9. guide rail.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Extremely shown in Figure 3 like Fig. 1; About the main body of the utility model gantry frame comprises two columns 2,4 and about two slides 1,6 and rigidly fixing be connected about the back timber 3 of two column upper ends, about two slides 1,6 lay respectively on the longitudinal rail on lathe bed both sides.Right column 2 rigidly fixes with right slide 1 and is connected; A supporting plate 5 is installed between left column 4 and the left slide 6; Supporting plate 5 is rigidly connected with the left column 4 of its top; There are two horizontal parallel guide rails 9 slide 6 upper surfaces, a left side; Match with guide rail 9 on the left slide 6 in the lower surface of supporting plate 5, the bearing of trend of guide rail 9 is vertical with the longitudinal rail on lathe bed both sides; The outside of left side slide 6 is extended with a holder 7, and an interior cyclic balance oil pressure cylinder 8 is installed on the holder 7, and the outer end of supporting plate 5 is connected with the piston rod of oil cylinder 8.
Above-mentioned " left side " and " right side " only are the relative positions to the gantry frame both sides, are not the qualification to the utility model.Can above-mentioned " left side " the unified change be " right side ", " right side " unified change is " left side ", not change the described structure of the utility model.
Before the work, be full of the pressure oil that adheres to specification for interior cyclic balance oil pressure cylinder 8.
In the work, gantry frame integral body is along the guide rail lengthwise movement of lathe bed.Because between supporting plate 5 below the left column 4 and the left slide 6 is to be slidingly matched; The outer end of supporting plate 5 is connected with the piston rod of oil cylinder 8; Therefore, when the horizontal internal stress variation of gantry frame reached the rated value of designing requirement, the overflow valve in the interior cyclic balance oil pressure cylinder was just opened off-load automatically.At this moment, left column 4 certain distance that will under the guiding of supporting plate 5, outwards squint, and cooperating still as before of left slide 6 and bed ways so just guaranteed the normal operation of gantry frame, and can not influence the machining accuracy of lathe.
